Acts 1:9
After he said this, while they were watching, he was taken up, and a cloud hid him from their sight — the cloud (nephele) recalls the glory-cloud (Shekinah) in OT theophanies, marking Christ's entry into divine presence and vindication. The bodily ascension in plain sight establishes that the risen Jesus is not a ghost or vision but the glorified humanity that sat at the right hand of God. The apostles' watching confirms the historical reality and their status as eyewitnesses.
